Sunderland have announced that assistant manager Paul Bracewell has left the club with immediate effect.
A statement on the club's official website on Saturday confirmed that he will step down, however, as the search for a new head coach goes on.
"It has been a great honour to serve Sunderland AFC as a player, coach and assistant manager for a combined total of 10 years," Bracewell said.
"I would like to thank the club and its staff, but also the supporters for the great backing I have received throughout my Sunderland career. I now look forward to the next challenge in my football career."
The Black Cats have now put their search for a new manager on hold while pushing through a sale of the club.
